SIX-HIT Rotherham United ran riot on their way to their first home win of the season as they ruined Bolton Wanderers' away party.
The visitors, backed by a sold-out away following in carnival mood, were playing their first League One match since being saved by a takeover and making a glut of deadline-day signings.
But the Millers, inspired by Ben Wiles, survived an early scare when they fell behind to play their best football of the season and could have added even more goals to their tally.
Record signing Freddie Ladapo opened his home account with a double and there was also a brace for Carlton Morris and the sun shone literally and figuratively at AESSEAL New York Stadium.
Bolton's vocal support was in raptures after only four minutes when Thibaud Verlinden jinked in from the left and fired home to launch Wanderers' new era.
However, the Millers kept their nerve and hit back to score three times in each half.
Wiles eased the home tension with a wonderful 14th-minute equaliser as he lifted the ball over an opponent's head before running in and bending a perfect low shot into the bottom far corner.
Freddie Ladapo miscued horribly in front of an open net six minutes later and soon after headed on to the bar but the £400,000 striker's first New York goal wasn't long in coming.
Just before the half-hour mark he took possession just inside the penalty and drove the ball past goalkeeper Remi Matthews.
Daniel Iversen rescued the Millers in the 34th minute with a superb save from Verlinden that was admired by everybody except referee Seb Stockbridge who missed it completely and awarded a goal-kick.
With half-time approaching, Carlton Morris nodded home his first goal since his loan switch from Norwich City to put Rotherham in the driving seat.
Having taken control of the contest, Paul Warne's men killed it within 10 minutes of the restart as Ladapo headed home a superb Jamie Lindsay cross and Morris saw his shot deflected in.
The chances were racking up for the Millers, with Ladapo, Jake Hastie and Morris all trying their luck, and Hastie, having scored on his debut a week earlier, added to the second-half domination with a 66th-minute tap-in.
Joe Mattock almost added an 83rd-minute seventh but flicked Wiles' corner over at the near post and Ladapo grazed the bar with a shot in the 87th minute as he chased his hat-trick.
Bolton fans did most of the singing. But it was the Millers who were on song.
